STRAW-CONVEYER.

SPECIFICATION forming part of Letters Patent No. 531,041, dated December 18, 1 894. Application filed March 29,1894. Serial No. 505,604.. (No model.)

To all whom it mayhoncern:

Be it known that we, WILLIAM LOUIS J OHN- soN and WILLIAM LAFAYETT HAY, residing at Franklin, in the county of Williamson and State of Tennessee, have invented certain new and useful Improvements in Straw-Conveyors for Thrashing-Machin'es, of which the following is a specification. V

Our invention relates mo'reparticularly to air blast stacking devices for thrashing machines, audit has primarily for its object to provide a conveyer means which can be readily attached to any of the modern styles of thrashing machines, which can be conveniently secured to the discharge end of such thrasher and which can be quickly and easily thrown up and back onto the top of the machine, whereby to give the thrasher man full 7 7 access to all the working parts of the thrasher,

when it is desired to clean and adjust the sieves, or for any other purpose required.

It has also for its object to provide simple, effective and easily operated means for adjusting the straw chute or conveyer laterally and vertically.

Furthermore ithas for its object to provide air blast attachments which are so arranged and constructed, that the air blast can be the more effectively regulated, to discharge onto the sieves and into the conveyer.

With other objects in view, which will hereinafter bereferred to, the invention consists in such novel arrangement and peculiar combination of parts as will be first described in detail and then pointed out in the claims,'reference being had to the accompanying drawings, in which- Figure 1 is a longitudinal section of the rear portion of the thrashing machine with our improvements applied. Fig. 2 is a side view thereof the conveyor being shown thrown up and back onto the top of the-thrasher, in dotted lines. Fig. 3 is a plan view of the end of the thrasher, and the conveyor, and showing such conveyer adjusted to a lateral position in dotted lines. Fig. 4 is an inverted plan view of a portion of the conveyer'frame and the adjusting worm shaft and rack. Fig. 5 is a detail horizontal section taken on the line 55, Fig. 2, and Fig. 6 is a transverse section on the line 6, Fig. 2.

ordinary construction.

0 beyond the rear end thereof and with such Referring to the accompanying drawings, A indicates the thrasher frame, B the combined carrier and separator and G the final separating screen, all of whichmay be of the Over the rear end of the carrier B, is arranged the rotary conduc tor or beater D, which is operated by the belt d, which is driven by the supplemental fan shaft E, on which is held the fan F which op.- erates in the casing G, the mouth of which discharges upward into the conveyor attachment as clearly shownin Fig. 1.

At the lower end and in front of the screen 0 is disposed the main blast chamber H, in which is journaled a fan I, and which has an upper and lower discharge flue H H the upper one H of which projects to discharge over and under the screen 0 and has a gate h, having in practice a handle portion extended without the side of the machine,whereby it can be readily adjusted from the outside. It will be noticed'the lower portion of the flue member H extends under the screen member H the lower member H (which passes under the transverse grain conveyer J) extends up and discharges into the said member H. It will be manifestly understood that by adjusting the gate 71. the quantity of air blast over and under the sieve C can be regulated as may desired, such parts being however so arranged that no matter how adjusted the combined blast from the members H and H condenses at the rear and discharges into the conveyer chamber, if desired.

Means are however provided for causing the chaff separated fromthe grain at the lower sieve to pass out sidewise instead of with the straw into the conveyer, when so desired, and to this end, a detachable cap or trough K is fitted onto the rear ordischarge mouth h, of the blast chamber H, which inclines transversely and projects through the side of the machine as shown at h it being however obvvious that by removing the said trough K the chaff will blow out with the straw into the conveyer.

The conveyer or st'raw carrier comprises an inner or base portion L, which is hinged as at Z to the upper and rear end of the machine casing, and such portion has its rear face inclined to snugly fit against the rear edges of the said frame, and form when in operative position, practically a continuance of such frame,such rear face of the conveyer having an opening or mouth Z the upper end of which registers with an inclined or deflector board I disposed over and to the rear of the conductor fan I, and the bottom of such conveyer inclines upward from thebottom of the thrashing chamber and has at its ends extensions or handle portions M, M, as most clearly shown in Figs. 1 and 4.. The upper and lower front ends of the portion L terminate in circular or disk like members L L, which are lapped by similar disk like members N N, of the chute member N, the bottom and top portions of which have circular seats or joints a, n which snugly fit against the front edges of the members L L, and such members N are pivotally joined to the members L by the pivot bolts 02, 01.

To allow for a free lateral movement in either direction the front portion of the section N, is formed with open sides which are held closed by wing like portions 0, hinged at one end to the sides of the section L as most clearly shown in Fig. 5, and having their free ends beveled as at o and held to engage guard plates N which form the rear extremities of the side portions of the chute section N, such wings being held to be moved inward and outward by the movement of chute section N, through the medium of short studs n, which project up on the inside of the wing portions 0 as most clearly shown in Fig. 6. l

P indicates the stack end member of the conveyer, which has a rule joint connection with the outer end of section N, its top and bottom boards being tapered to fit into the end of such section as clearly shown in Fig. 1. The interior of the conveyer, and its rear edge, are preferably covered with gum cloth to make the several joints practically'air tight.

An arm 23 is projected up from the top of the stack section P, to which is connected a chain or rope Q which passes rearward and is wound on a Windlass shaft R mounted on the top of the machine as shown.

By referring now more particularly to Fig. 3 it will be seen the bottom of conveyer section N has a downwardly extending member N formed with a segmental cog rack N, with which engages a worm shaft L journaled transversely on the bottom of the section L, which shaft has at one end an operating handle, such construction providing a simple and effective means whereby such section N, can be quickly and conveniently adjusted by a person standing on the ground, and moved laterally to either side. If desired such means may be dispensed with, and a Windlass S journaled on top of the machine may be used, to which is secured one end of chains or ropes T which are wound thereon in opposite directions, their free ends being secured to the section N as clearly shown in Fig. 1.

From the foregoing description taken in connection with the drawings it is thought the advantages and complete operation of our improved devices will be readily understood. It will be noticed that the conveyor is so hinged to the body of the machine, that two men by taking hold of the handle members M, can quickly fold it back on top of the machine, and then when the chains '1 are used can be held down by winding up the Windlass S, such conveyer being also quickly brought to its operative position by pulling down on the handles M.

By providing the wing members 0, simple and effective joints are provided, substantially air tight, avoiding the necessity of using cuff like or supplemental inclosing casings usually employed for such purpose.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

1. As an improvement in pneumatic straw conveyors for thrashing machines, the combination with the main frame and the conveyer section, of a main blast tube having its discharge end at the mouth of the conveyer section, a detachable cap or spout for such end, and a supplemental blast chamber having its discharge mouth opening into the conveyer section substantially as shown and described.

2. In a pneumatic straw carrier for thrashing machines, a blast chamber having a main and supplemental discharge tube, the lower or supplemental tube, discharging into the main tube, and a transverse removable cap or spout adapted to fit onto the discharge end of the said blast chamber and projected to one side of the machine, all arranged substantially as shown and described.

In a pneumatic straw conveyer, for thrashing machines, the combination with the main frame, the stacking or conveyer tube section and the lowest or final screen, of a blast chamber having two discharge tubes, one of which discharges at the front end of such screen, over and under it, and having a regulating valve, the other of which passes rearward and discharges under the screen into the first tube, such first tube held to discharge into the conveyor section at a point under the rear end of the said screen all arranged substantially as shown and described.

4.
